[Solved] Please tell me the code of the elements

We don't see such an issue. Please see how it looks in our case:

This is not a plugin issue!

I just want to hide in the mobile version the hints that appear when you click on the icons of the two filters and the user data icon.

This code worked successfully:

@media screen and (max-width: 1024px) {
.wpd-filter.wpdf-reacted[wpd-tooltip]::after {
display: none!important;
}
.wpd-filter.wpdf-hottest[wpd-tooltip]::after {
display: none!important;
}
.wpdiscuz-user-settings.wpd-info[wpd-tooltip]::after {
display: none!important;
}
}

But this code only hides the rectangular parts of the hints. Little triangles/arrows remained unhidden!

Of course they are visible when touching/clicking on the filter.

Please tell me the code for these triangles/arrows. I would like to hide them too.

I am waiting for your reply

@yuri-vasilchenko,

Here is a code you can use: 

 .wpd-filter.wpdf-reacted[wpd-tooltip]::before {display: none;}

@asti

Yes, it works great. Thank you!
